Description

Technical Field

[0001] This utility model specifically relates to a device for removing impurities during deep processing of rice, belonging to the field of rice processing technology. Background Technology

[0002] Rice grains consist of the husk, bran, embryo, and endosperm. The purpose of rice processing is to separate the endosperm from the other parts with minimal breakage, producing rice of good eating quality. This process involves removing the husk (chaff) and bran (thin layer) from cleaned rice. The weight percentages of each part are: husk 18%–21%, bran approximately 6%, endosperm 66%–70%, and embryo 2%–3%. The chemical composition of each component varies considerably (see table). The husk contains up to 40% fiber, with little nutritional value; the bran is rich in protein and fat, but also high in fiber; the embryo contains a large amount of protein, fat, and vitamins; and the endosperm contains the most carbohydrates and the least fiber. The goal of rice processing is to separate the endosperm from the other parts with minimal breakage, thereby producing rice of good eating quality.

[0003] In existing rice deep-processing impurity removal devices, magnetic separation devices are a common type of impurity removal device. The permanent magnet drum is the core component of the magnetic separation device, mainly used to adsorb magnetic impurities such as iron filings and metal fragments. However, when too much iron filings and fragments are adsorbed on the outside of the permanent magnet drum, it will cause the magnetic force of the permanent magnet drum to weaken and the magnetic field strength of the permanent magnet drum to be weakened, making it impossible for subsequent iron filings to be effectively adsorbed. Some metal impurities will be mixed into the finished rice. Metal impurities that are not cleaned in time will enter subsequent processing equipment (such as rice milling machines and polishing machines) with the rice, which may cause wear and tear on mechanical parts and shorten the life of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the problems in existing technologies where the magnetic force of permanent magnet drums weakens, resulting in reduced magnetic field strength and preventing the effective adsorption of iron filings. This leads to some metal impurities mixing into the finished rice and entering subsequent processing equipment with the rice. The invention provides a rice deep-processing impurity removal device that allows scrapers to efficiently remove metal impurities adsorbed by the drum during drum rotation. The scraping mechanism cleans the drum surface in real time, maintaining magnetic stability and solving the problem of magnetic force attenuation caused by metal accumulation in traditional magnetic separators. This eliminates the need for manual cleaning and improves continuous operation efficiency.

[0005] A device for removing impurities during deep processing of rice includes: a support shell, a magnetic suction mechanism, a dust removal mechanism, and a scraping mechanism;

[0006] Scraping mechanism, including a cleaning component and a clamping component. The cleaning component is used to scrape and clean the iron filings and metal fragments magnetically adsorbed by the magnetic adsorption mechanism mechanically, and the clamping component is used for the quick disassembly and assembly of the cleaning component;

[0007] The cleaning component includes a scraper and a first spring. One side of the scraper is designed to be arc-shaped. The clamping component includes an insertion plate and an assembly block. One side of the assembly block contacts one end of the first spring. A positioning groove is opened inside the assembly block, and the insertion plate can be inserted into the positioning groove in a matching manner.

[0008] Further, two groups of support rods are arranged on the outer side of the support shell, and clamping grooves are penetrated and opened inside both groups of support rods.

[0009] Further, a storage shell is arranged between the two groups of support rods. A limiting plate is arranged on one side of the storage shell. The limiting plate is designed in a "convex" shape. A blocking plate is movably arranged inside the limiting plate. One side of the storage shell is provided with a first electric push rod above the limiting plate. The bottom end of the rod body of the output end of the first electric push rod is connected to the upper surface of the blocking plate.

[0010] Further, the magnetic adsorption mechanism includes a drum and multiple groups of magnets. The multiple groups of magnets are arranged in a circular equidistant array inside the drum. Shaft bodies are arranged at both ends of the drum. Bearings are sleeved on the outer sides of two of the shaft bodies, and the bearings are respectively arranged in the two clamping grooves. One end of one of the shaft bodies is provided with a first gear. A motor is arranged on the front surface of the support rod by means of a bracket. A second gear is arranged at the output end of the motor, and the second gear is meshed and connected with the first gear.

[0011] Further, the dust removal mechanism includes an air extraction component and a filter screen. An assembly shell is arranged between the two groups of support rods below the drum, and the assembly shell penetrates through the bottom end of the support shell. The air extraction component consists of an installation cylinder and a fan. The air extraction components are arranged in an equidistant array inside the assembly shell, and the filter screen is detachably arranged inside the assembly shell.

[0012] Further, an installation frame is movably arranged inside the support shell. A screen is embedded inside the installation frame. Multiple groups of connecting rods are arranged on the upper surface of the installation frame. The connecting rods are in the shape of "L" plates. Four groups of guiding frames are arranged on the upper surface of the support shell, and the four groups of guiding frames penetrate through the inside of the four groups of connecting rods. Two groups of second electric push rods are arranged on the upper surface of the support shell. One end of the rod body of the output end of the two groups of second electric push rods is connected to one side of the other two groups of connecting rods.

[0013] Further, a blanking shell is penetrated and arranged inside the bottom end of the support shell. A diversion plate is arranged obliquely at the bottom end of the support shell, and the diversion plate is located below the installation frame.

[0014] Furthermore, the bottom of the storage shell is provided with two sets of mounting plates, and a guide rod is movably installed inside the interior of each set of mounting plates. The first spring is located on the outside of the guide rod, the assembly block is located at one end of the guide rod, and a second spring is located on the outside of the rod body on the front of the insert plate, wherein the rod body is movably installed inside the plate on one side of the scraper.

[0015] Beneficial effects:

[0016] By incorporating a scraping mechanism, the second spring on the outer side of the insert plate exerts elastic pressure on the insert plate, allowing it to be inserted into the positioning groove inside the assembly block. This enables the scraper and assembly block to be positioned and assembled, facilitating quick disassembly and assembly of the scraper and simplifying maintenance. The first spring on the outer side of the guide rod exerts elastic pressure on the assembly block, ensuring stable scraping force of the scraper on the roller. The scraper's arc-shaped design conforms to one side of the roller surface, efficiently removing metal impurities adsorbed by the roller during its rotation. The scraping mechanism cleans the roller surface in real time, maintaining stable magnetic force and solving the problem of magnetic attenuation caused by metal accumulation in traditional magnetic separators. It eliminates the need for manual cleaning during machine shutdown, improving continuous operation efficiency.

[0017] Equipped with a dust removal mechanism, the fan inside the exhaust assembly generates negative pressure to suck away light impurities, such as bran powder and dust, falling from the rice into the storage shell. The filter inside the assembly shell filters out light impurities from the extracted air. The filter is removable for easy cleaning of accumulated dust and to maintain smooth airflow. By combining the exhaust assembly with a magnetic suction mechanism, magnetic metals and dust can be removed simultaneously, improving the cleanliness of rice processing. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a device for removing impurities during deep processing of rice;

[0029] Includes: support shell 1, magnetic suction mechanism, dust removal mechanism and scraping mechanism;

[0030] The scraping mechanism includes a cleaning component and a locking component. The cleaning component is used to mechanically scrape away iron filings and metal fragments magnetically attracted by the magnetic attraction mechanism, and the locking component is used for quick assembly and disassembly of the cleaning component.

[0031] The cleaning assembly includes a scraper 30 and a first spring 25. One side of the scraper 30 is designed in an arc shape. The locking assembly includes an insert plate 28 and an assembly block 26. One side of the assembly block 26 contacts one end of the first spring 25. The assembly block 26 has a positioning groove 27 inside, and the insert plate 28 can be inserted into the positioning groove 27. The bottom of the storage shell 3 is provided with two sets of mounting plates 23. Guide rods 24 are movably installed inside the two sets of mounting plates 23. The first spring 25 is located on the outside of the guide rod 24. The assembly block 26 is located at one end of the guide rod 24. A second spring 29 is provided on the outside of the front rod of the insert plate 28, and the rod is movably installed inside the plate on one side of the scraper 30.

[0032] By having the assembly block 26 contact one side of the scraper 30, and the positioning groove 27 inside the assembly block 26 located behind the insert plate 28, the elastic squeezing force of the second spring 29 on the outer side of the front of the insert plate 28 can make the insert plate 28 insert into the positioning groove 27 inside the assembly block 26, thereby achieving the positioning assembly of the scraper 30 and the assembly block 26, which facilitates the quick disassembly and assembly of the scraper 30 in the later stage and makes maintenance easier.

[0033] The guide rod 24 moves through the interior of the mounting plate 23. The elastic squeezing force of the first spring 25 on the outside of the guide rod 24 on the assembly block 26 allows the arc-shaped surface of one side of the scraper 30 to fit against the roller 8. The arc-shaped design of the scraper 30 fits against one side of the roller 8. During the rotation of the roller 8, the scraper 30 can efficiently scrape off the metal impurities adsorbed by the roller 8, solving the problem of magnetic force attenuation caused by metal accumulation in traditional magnetic separators. There is no need to stop the machine for manual cleaning, which improves the efficiency of continuous operation. The first spring 25 is used to elastically press the scraper to ensure stable scraping force.

[0036] The support shell 1 serves as the main framework, carrying core components such as the magnetic attraction mechanism and the dust removal mechanism to ensure the stable operation of the device. The support rod 2 is used to provide installation support for the storage shell 3 and the assembly shell 13. The roller 8 can be rotatably arranged in two groups of clamping grooves 7 by means of bearings on the outer sides of the shaft bodies at both ends. After installation, the upper surface of the iron roller 8 can come into contact with the rice falling from the storage shell 3. The iron roller 8 is internally provided with multiple groups of circular magnets 9 arranged at equal distances, forming a uniform strong magnetic field. By the cooperation of the roller 8 and the magnets 9, iron filings and metal fragments in the falling rice can be adsorbed. The second gear 12 at the output end of the motor 11 is meshed with the first gear 10 at one end of the shaft body of the roller 8. Driven by the motor 11, the second gear 12 can drive the first gear 10 to slowly rotate the roller 8, ensuring that the roller 8 continuously adsorbs the rice falling from the storage shell 3. The array design of the magnets 9 enhances the magnetic field coverage and avoids adsorption dead corners. The bearing support structure (clamping groove 7) reduces friction loss and extends the service life.
